.T LZZ whom, it r11/ay concern;

Be it known that I, RODERICK MURoHisoN, a citizen of thel United States,residing at Kewanee, in the county of Henry and State of Illinois, haveinvented certain new and useful Improvements in Drilling Attachments forCorn-Planters, of which the following is a specification. v

The invention herein described relates to 1o improvements incorn-planters and the leading object of the invention is to providedrill- .ing attachments for that class of check-rower corn-planters inwhich an intermittently-rotating seed-cup disk or wheel in the seedboXand a discharging valve or valves in the seedtube are operated byarock-shaft, which rockshaft is given motion in one direction by atappeted check-row line stretched over the ground being planted and inan opposite or zo everse direction by a spring or equivalent device.

- Further objects of the invention are to provide such drill attachmentsfor check-rower corn-planters of the class described, which at- 2 5tachments are simple and cheap in construction, certain and efficient inaction, readily and easily applied to different makes of checkrowers ofthe class referred to, not liable to get out of order, which will notoperate in 3o backing the machine, and can be easily and quickly throwninto and out of gear with their operating mechanism.

For the purpose of carrying out these objects the invention consists innovel struc- 3 5 tural features and novel organization and combinationsof parts,th e operations of which parts as organized and combined arehereinafter fully described, and the construction and combination ofwhich parts are made the 4o subject-matter of the appended claims.

In the accompanying' drawings,which illustrate my invention, Figure 1 isa top plan of one side part of a` check-rower corn-planter with part ofthe wheel-rim broken away and the seedbox in section embodying myinvention. Fig. 2 is a side elevation of the parts shown at Fig. 1 withthe check-row line removed and part of the wheel broken away; Fig. 3, asectional elevation of parts 5o and side elevation of other parts in theline 3 3 in Fig. 1, but showing a portion of the drill attachmentdifferently adjusted from that shown at Fig. l; Fig. 4, an enlarged topplan of a portion of t-he drill attachment; Fig. 5, an enlargedsectional plan of the seedbox and plan of parts adjacent thereto; Fig.G, an enlarged side elevation of the lower part of the secdbox and upperend of the seed-tube and adjacent parts, partly in section and partly inelevation; Fig. 7, an en- 6o larged side elevation, partly in section,of a portion of the drill attachment.

My drilling` attachment can be applied to any check-rower corn-planterof that class or type in which a rock-shaft operated by a check-rowerline having tappets is the medium through which intermittent rotarymotion is given to a seed-cup disk or wheel in the seedbox and aseed-discharging valve in the seed-tube. 7o

In the present instance I have shown the invention adapted to acheck-rower planter of an ordinary type and ordinary construction, withtransverse frame-bars 1, side frame-bars 2, braces 3, split wheels 4,seedboXes 5, seedcup disks b', rock-shaft 7, forked levers S, runners 9,seed-tubes 10, seed-tube valves 11, valve-openers 12, and check-rowerline 13 with tappets 14,' the operation of which is in an ordinarymanner and may be briefly de- 8o scribed as follows:

A forked lever 8, contacting successionally with the tappets 14 of thestretched wire, will be swung rearwardly thereby and will thus give aswing or oscillatory movement in one direction to the rock-shaft 7, andthis movement of the rock-shaft, by means of the radiusarln 15,connected with the rock-shaft, will give a forward throw to the pawl 16,and its forward end coming in contact with one of the 9o ratchet-teeth17 on the under side of the seedcup disk 6 will give a partial rotationto said disk and bring one of its holes or cups 19, with its charge ofseed, under the cut-off 20 and over the discharge-opening 21 in the bot-95 tom of the seedbox, whence it passes downward in the hollow tube 10to the spring-valve 11 and is there detained until discharged by thedownward movement of the valve-opener 12, which occurs at eachsucceeding movement in the direction described of the rockshaft, bymeans of the radius-arm 22, which projects from the rock-shaft and ispivotally connected with the valve-opener 12. When the forked leverescapes from a tappet 14, the spring 23, which connects a forked leverwith IOO an arm 24, projecting from a l`ra1ne-bar, will give a returnmovement tothe rock-shaft and thus restore the pawl 1G to its normalposition and also retract the valve-opener 12 to its normal shownposition. The pawl 1G is held in contact with the ratchet-teeth 17 bymeans of a spring 25, andthe seed-cup wheel is held from backwardmovement by means of a spring-actuated detcnt-pawl 2G. Ordinaryguide-pulleys 27 direct the cheek-rower line properly to the forkedlever. An ordinary line-doi'er 2S is shown, but need not be herei ndescribed. The seed-cup disks 6 are substitu tive in the usual mannerfor others having larger or smaller seed-cups for varying the quantityor number of seed dropped in each hill and for thinner disks and smallseed-cups for dropping a single grain in each charge.

When the drilling attachment is used, the check-rower line is dispensedwith and a thin seed-cup plate is used in the seedbox to separate singlegrains of seed from the mass in the seedbox and deliver such charges ofsingle grains to the seed-tube at each intermittent movement of theseedscup plate or disk. The drilling attachment in this instancecomprises a bent arm or lever 2f), having an integral hollow journal 30projecting laterally therefrom and through a bearing 3l, which is fixedto a plate 32,that is bolted to a side framebar 2. The journal 30 isheld in the bearing 3l bya bolt 33. (See Fig. 4.) The arm or lever 20has an extension 34 hinged toits rear end part by a pivot-pin 35, Fig.7, in such manner that said extension may be oscillated or swung in avertical plane; The downward swing of this extension is limited byshoulders 3G thereon coming in contact with shoulders 37 on the rear end38 of the main part of the lever, Fig. 7, and its upward swing islimited by shoulders 39 thereon coming in contact with the upper side ofthe main rear part 33 of the lever, as shown by full lines at Fig. 3 anddot-lines at Fig. 2, in which turned-back position it will sustainitself, as its upper portion is inclined back of or past its pivotalpoint. 'lhe outer end of the forward end part 40 of the arm or lever 29is pivotally connected by a link 4l with the outer end of anupwardlyprojecting radius-arm 42,whieh projects from the rack-shaft 7.lVhen the extension 34 is in its horizontal position,as shown by fulllines at Figs. l, 2, and T, its rear end part is within the orbital pathof a circular series of tappetpins 43,which project axially from anannulus or ring-shaped plate 44, which is bolted to the spokes of one ofthe plan ter-wheels. The anuulus 44 may be otherwise constructed andfixed in place, and may in case oi? a rotating axle be iixed thereto.

The tappct-pins 43 preferably have each a loose antifrictionsleeve 45mounted thereon, and as these tappets successionally come into contactwith the lever 29 or its rear eXtension each of them turns or swingssaid level' in one direction on its pivotal point, the journal 30, andin doing so forces the rear end of said lever downwardly and its forwardend upwardly and baekwardly into the position shown by dot-lines at Fig.2, and the lever 29, as it swings into such position, will by means ofthe lilik 4l draw the radius-arln 42 backwardly at its outer end andthereby swing or oscillate the rock-shaft 7 in one direction, the samedirection that it is moved by the tappcts on the check-rower line, andthereby give a partial rotation to the seed-cup wheel and movement tothe discharging-valve in the seed-tube, the same as is given to saidparts by the tappets on the check-rower line. Immediately after theescape of each tappet-pin 43 from the rear extension of the lever 29 thespring 23 not only restores the valve and valveopener in the seed-tubeand the pawl which actuates the seed-cup wheel to their normalpositions, but also, by means of the arm 42 and link 4l., restores thelever 29 to its normal position, as shown by full lines at Fig. 2, andready for the action of the next succeeding tappet-pin 43.

The extension 34 of the lever 29 will not interfere with backing theplanter, as it will swing upwardly, as shown by dot-lines at Fig. 3,whena tappet-pin 43 eomesin cont-act therewith, and thus permit of said pinspassing the lever as the planter-wheel turns backwardly. The driver maywith his foot or by other m cans turn the extension 34 upwardly, asshown by full lines at Fig. 3 and dot-lines at Fig. 2, where it willremain, and while in such position the tappetpins 43 will not come incontact therewith, and hence will not operate the drilling mechanism inturning the planter around at the ends of rows, in movingit from placeto place, or in moving it over ground where planting is not desired, andwhile the lever 29 is otherwise in operative position i'ordrill-planting.

rlhe tappet-pins 43 are at such short distances apart that they willoperate the seedcup' disk much more rapidly than is done by thecheck-rower line, and hence make the deposits of the single grains ofseed at short distances apart, as is usual in drill-planting. Thestarting and stopping of the intermit tently-rotating seed-cup plates atthe passage of each seed-cup beneath the cutoff will, by the slight jarsgiven thereby to the seedcups in contact with the seed in the seedbox,tend to effect a complete settlement of the singlegrain charge in eachseed-cup before it passes beneath the cut-oli', and hence produce regular dropping of such charges of seed, which is not accomplished by acontinuously-rotating seed-cup plate.

The use of the lower valve in drilling, by dropping the single grainsfrom a point near the deposit of the seed in the soil, will securesubstantially accurate dropping of the grains at uniform distancesapart, which is not done when the grains fall from the. seed-cup disk tothe place of deposit and sometimes fall direct, while at other timesthey strike the sides of the seed-tube duct, and are also affected IOOIIO

more or less in thisrespect by changes in the rate of speed of theplanter in operation. If preferred, however, the lower valve may beremoved when the planter is used as a drill.

In the use of this planter in check-row planting the seed-cup plates arechanged, as described, and the check-rower line used in the ordinarymanner, and the drilling attachment can be thrown out of gear to notinterfere with check-row planting, as hereinbefore described, by simplyturning the extension 34 into the position shown by full lines at Fig.3. The link 4l may also, if preferred, be disengaged from the radius-arm42. The lever and link will then remain in position where they can bequickly and readily adj usted for drill-planting.

I do not claim as my invention the adjustable plate 47 as a cover forthe opening in the upper end of the seed-tube.

What I claim as new, and desire to secure by Letters Patent, is
